ResumoElectromagnetic emissions from lightning flashes are observed by a slitless spectrum spectrograph. A Phantom V9.1 high-speed camera is used with a spatial resolution of 1632 x 400 pixels, at 3000 fps and exposure time of 330 μs. A grism (diffraction grating plus prism) that has 600 lines/mm and a spectral ranger 600-1050 nm were coupled to this camera. The lightning observations were made in the city of São José dos Campos (latitude: 23° 11'25.15''S, longitude: 45°53'3.44''W), Sao Paulo, Brazil, focusing on cloud-to-ground lightning events, with both negative or positive polarities. Data from sensors of the BrasilDAT and RINDAT networks were also used to gather additional information (location, polarity and peak current estimation). The objective of this work is to observe for the first time the time-resolved characteristics of lightning emission in the near infrared in Brazil.

ResumoDuring the summer season of 2012, a network of high-speed cameras, called RAMMER network, recorded two bipolar flashes produced by a thunderstorm that occurred on March 13th. Data from BrasilDAT network provided location and peak current information for the events. Additional RAW data from the sensors, allowed more detailed analyses. Both bipolar flashes presented multiple negative return strokes, and there was intense recoil leader activity bellow cloud base. The objective of this work is the evaluation of the peak currents of those recoil leaders. The bipolar nature of these flashes allowed a unique way to calibrate the camera luminosity with the stroke peak currents estimated by the local lightning location system (LLS). Recoil leaders are commonly visible below cloud base during positive flashes development, but have not yet been observed during negative flashes in a similar fashion. The bipolar flashes observed had one positive return stroke and multiple negative return strokes that were used in the calibration process. In order to evaluate the recoil leaders peak current, the luminosity levels of each video were calibrated using the unsaturated pixel brightness levels during the negative return strokes and the data from the BrasilDAT LLS. The same high-speed camera used during the observation campaign was tested in laboratory to determine its CMOS sensor response curve. Through a scatter diagram of luminosity (estimated from the pixel intensity values) versus estimated peak current (provided by the BrasilDAT network), it was shown that both physical quantities are related. The calibrated pixel values were used to create equations to calculate the recoil leader peak currents. A total of 281 recoil leaders were identified, 191 in flash #1 and 90 in flash #2. Results show that recoil leader estimates are closely related to previous observations of cloud discharges by LLS. The geometric mean value was 1.06 kA, with a maximum of 7.7 kA. Less than 14% presented peak currents comparable to weak return strokes (> 2 kA).

ResumoThe objective of this work is the analysis of overall characteristics of 35 cloud-to-ground (CG) strokes that presented two or more contact points to the ground in a millisecond scale. This dataset includes both the classical forked strokes (first observed in streak camera records) and the new class of this type of phenomenon, called upward illumination strokes, introduced in more recent works. The genesis of the latter is very similar to the classical forked strokes, i. e., one branch from the main trunk of a stepped leader produces a second stroke after the first return stroke occurs. The main difference from the classical forked stroke events are: a) UI stroke channels appear to completely disconnect from the main trunk during its development, b) the time between strokes is longer than in the case of classical forked strokes and c) the peak currents of the UI strokes are, usually, very small. From the visual inspection of the 35 selected events, 22 were classified as forked strokes and 13 UI strokes. A new name was given to the broad class of strokes that present two or more contact points in a millisecond and sub-millisecond scale, multi ground contact strokes (MGCS). Subclasses received the names forked strokes and UI strokes, related to the previous findings from the literature. All MGCS flashes were recorded during the summer season of 2013 in Southeastern Brazil as part of a five-day campaign employing a network of high-speed camera sensors known as the RAMMER network. The high-speed video records were obtained by three identical cameras installed in São José dos Campos and a fourth mobile camera (whose only difference from the other three is its capability to record colored images). All four cameras were set up for recording at 1200 x 500 pixels spatial resolution, 2500 frames per second, and 400-μs time interval between frames. A total of 357 negative CG flashes were recorded. The physical processes that generate either forked strokes and UI strokes are discussed in details. RAW data from BrasilDAT network was used to identify and give more information about the MGCS, such as: peak current estimates and precise interstroke intervals in the microsecond range. Plots of time intervals between strokes versus peak current added new information on the physical characteristics and distinctive features of UI and forked strokes.

ResumoHigh-speed video records of two bipolar cloud-to-ground flashes were analyzed in detail. They were both initiated by single positive return strokes and were followed by more than one subsequent negative stroke. Due to the elevated cloud-base height of its parent thunderstorm, the initiation processes of each subsequent stroke could be registered optically below cloud base. In the first event (Case 1) it was possible to observe that all four subsequent negative strokes were initiated by recoil leaders that retraced one horizontal channel segment previously ionized by the positive leader that preceded the first stroke. Those recoil leaders connected to the original vertical channel segment and propagated towards ground, producing four subsequent strokes that had the same ground contact point of the original positive discharge. The second event (Case 2), on the other hand, presented fifteen subsequent strokes that were initiated by recoil leaders that did not reach the original channel of the positive stroke. They diverged vertically towards ground, making contact approximately 11 kilometers away from the original positive strike point. These are the first optical evidences that both single- and multiple-channel bipolar flashes occur as a consequence of recoil leader activity in the branches of the initial positive return stroke. For both events their total channel length increased progressively with time at a growth rate equivalent to a propagation speed of the order of 104 m/s, comparable to those reported for typical positive leaders.

ResumoDuring the early afternoon of 22 September 2013, severe storms, accompanied by large hail, damaging winds, heavy precipitation and dangerous lightning, devastated a region between 100 and 200 km south-southwest of the Bauru S-band Doppler radar. Several extremely intense storm cells moved at up to 100 km/h east-southeastward and at least one of them spawned a tornado when it reached the town of Taquarituba, in Southeastern Brazil. The synoptic pattern was very favorable for the development of severe weather conditions over southeastern Brazil, due to a cyclogenesis process that generated an MCS (Mesoscale Convective System), with a squall line inserted. The convective cells were tracked throughout their lifetime by IPMet´s Doppler radars. The cells intensified drastically, with towers overshooting into the stratosphere (10 dBZ ≤ 20 km) and shortly before reaching the town of Taquarituba, that particular cell displayed extremely strong radial shear just above the cloud base, which led to the formation of a deep meso-cyclone, from which the tornado spawned and touched down at around 14:30h LT. Before the tornado touch-down relatively few CG strokes were observed near the tornadic cell, but thereafter the frequency increased rapidly. The IC activity was extremely high at most times. WRF model proofed itself extremely efficient to forecast the severe thunderstorm.

ResumoOn December 10th through 11th 2012, a strong convection activity over southern Brazil grew into a huge Mesoscale Convective System (MCS) accompanied by heavy precipitation, hailstorm, damaging winds and dangerous lightning. The Civil Defense Authority reported that over 700,000 people experienced power outages due to either strong winds or lightning strikes or even suffered from flash floods caused by high rain volumes. The Brazilian Lightning Location System (BrasilDAT) detected more than 90,000 cloud-to-ground (CG) lightning strikes during the MCS activity, and approximately 4,000 CG strokes presented large peak currents over 75 kA. The main objectives of this work were to achieve the most suitable configuration of the Weather Research and Forecasting (WRF) model, and to apply the Potential Lightning Region (PLR) tool, in order to forecast reliably this type of severe weather event with enough time in advance to adopt strategies that might minimize injuries and hazardous situations in the future. Firstly, the CG and IC lightning stroke rates, the peak currents distribution, and the IC/CG ratio were evaluated. Observed precipitation from a homogeneous network of surface meteorological stations was used as proxy data. Lightning and precipitation were compared during the MCS development in order to seek for correlations. As well known, current operational models cannot predict convective subgrid scale processes explicitly, due to their microscopic and discontinuous nature, and must do so via parameterization. In this case, a cumulus scheme should try to transport heat vertically, redistribute moisture, and reduce thermodynamic instability. Four cumulus parameterization schemes (CPS) in the WRFv3.3.1 model were investigated to proper simulate this MCS over southern Brazil. WRF grid points near meteorological stations with high accumulated precipitation values were chosen in order to assess the behavior of the simulated data against the observations. The Potential Lightning Region (PLR) is a tool that indicates the spatial distribution of lightning occurrence probabilities in a given area. PLR was developed from a combination of WRF output variables, and operationally tested over southeastern Brazil. The WRF convective parameterization selected from the previous analysis was used to generate new PLR maps over southern Brazil for the MCS. This case study served as a laboratory to expand PLR capabilities in the prediction of severe weather events.
